Find X And Y Multiple Choice

Answers

Answer 1

Answer:

x=30

y=4

Step-by-step explanation:

Since there is an equilateral triangle, those angles =60°, and all sides to that triangle are equal.

You can determine y by looking at the congruent lines on the second triangle. In this triangle, we see that two sides, one of which is a side to the equilateral triangle, are equal to 20. Because one of these sides is a side to the equilateral, we know that all sides of the equilateral triangle are equal to 20, so using simple algebra you can determine that y=4.

To solve for x is a little more difficult. In the equilateral triangle, we know that all angles =60°, therefore we can solve for two angles to use to solve for x. We can solve for the obtuse angle by subtracting 60 from 180=120. then we can solve for the next angle that is next to the equilateral triangle because these two make a right angle so 90-60=30. Now you add the angles you just solved for, subtract that sum from 180, and you get x.

120+30=150

180-150=30

x=30

The stock of Company A lost $2.55 throughout the day and ended at a value of $57.45. By what percentage did the stock decline?

Answers

Given:

Loss = $2.55

Value of stock after loss = $57.45

To find:

The percentage by which the stock decline.

Solution:

We have,

Loss = $2.55

Value of stock after loss = $57.45

Value of stocks before loss = Value of stock after loss + loss

                                              = $57.45 + $2.55

                                              = $60

Now,

[tex]\text{Percentage by which the stock decline}=\dfrac{\text{loss}}{\text{initial value}}\times 100[/tex]

[tex]\text{Percentage by which the stock decline}=\dfrac{2.55}{60}\times 100[/tex]

[tex]\text{Percentage by which the stock decline}=4.25%[/tex]

Therefore, the stocks of the company declined by 4.25%.

Find m∠1. Then classify the triangle by its angles

Answers

9514 1404 393

Answer:

∠1 = 60°equilateral triangle

Step-by-step explanation:

The sum of angles in a triangle is 180°, so we have ...

  60° +60° +∠1 = 180°

  ∠1 = 180° -120° = 60°

The measure of angle 1 is 60°.

All of the angles are the same, so this is an equiangular triangle, better known as an equilateral triangle.

Solve for x:122+4x=3x+87​

Answers

Answer:

122+4x=3x+87

the first step is to move the variable and constants because we can not add variable and constants together we will move 3x and 122 it will be something like this: 3x-4x=122-87 now that the constants and variables have moved we can solve it because we moved them the addition symbol will become a subtraction symbol the answer will be: 1x=35

Step-by-step explanation:

122+4x=3x+87

3x-4x=122-87

1x=35

I hope this helped

If you were tovisit the American Southwest today, you might be disappointed with the lack of variation among cactusspecies, especially right off the major highways. In 1926, Route 66 was the nation's first major highway toallow visitors to visit the Southwest. Like many tourists, these visitors wanted to take home a memento oftheir travels. Many people would pull over and begin looking for their own living souvenir. Since many of thetourists did not have the necessary tools to extract a spiny cactus out of the soil, they usually had to make aconscious decision about what type of cactus they should dig up. The cacti with too many spines were seenas too difficult to dig out, and the visitors likely didn't have gloves to protect their hands. The cacti with toofew spines were seen as homely and were often overlooked. Therefore, the tourists found a cactus that wasbetween these two extremes. Over the last century, the phenotypic variation within these small cacti haschanged (at least in areas accessible by these highways).
